'aiiatimi of the zii- E: .mismsima cross saisi-i011 en nico the guarding Wires With opposite charges of potentiel on the ait/ernste Wires, and the .by the vcrticsl wires v and o and the horizontal Wires ii and it. The inner cage 3 has a charge maintained upon it and the outer cage et has e etici-ge of opposite potential as indicated. y

Referring to Fig. l end 1i the tvvo concentric cages composed of the vertical conductors 'viz/end the horizontal conductors lle-lf; 2Jis the antenne connected through the primary oscillation circuit P to the ground 5. S is the secondary oscillation circuit. The inner set of conductors 3 are connected through :i source of negative potential 6 to the ground 5. The outer set of conductors It are connected through a source of positive potential 7 to the ground 5.

Referring rto liig. 3y 3 and ere the guarding Wires surrounding the antenna 2;

. the inner set of Wires 3 being connected to the negative pole of asource of electricity 8 end the outer set ci wires t is connected to the mettrais pois of the source of electricity '8. The antenna 2 is connected to the pri mary circuit lj to the groundy S is the secondary receiving circuit.

.cferrmg to Fig. fltne two guarding sets of conductors are shown in horizontal vicw occu in substantially the same cylindrical :l u n.

. specs around; the antenna 2. This arrangement may be produced by connecting each alternate wire respectively to positive und negative sources of electricity as indicated. Having thus described our invention, what We claim and desire to secure by letters Pat ent isv l. ln e Wireless vreceiving station including a ineens for reducing the disturbing effects of 'atmospheric electricity, an antenna, a receiving circuit in connection With said antenna, means for detecting incoming electro-magnetic Waves iu combination with two seperate sets of conductors, scid sets ci conductors being insulated from and substantially surrounding said antenna, and means for impressing locally charges of electricity respectively upon seid sets of conductors.

2. ln e Wireless receiving station, including a means for reducing the disturbing eiects of static, en antenna, c. receiving circuit .in connection with seid antenne, ineens for detecting electro-magnetic Waves striking seid antenne in combination With twoscts of conductors, lsziicl conductors being separate trom and substantially surrounding scid antenne, and means for impressing charges-of opposite sign respectively upon said sets of conductors. A

B. in a wireless receiving station, including a means of improving the reception of electro-magnetic Waves, an entennef'freceiving circuit in connection with said antenne., and means for detecting electro-magnetic Waves in combination with two Se arcte sets ot conductors, said conductors eing seperate from and substantilly surrounding said antenna, and means for impressing :md maintaining charges of opposite character respectively between said two sets of conductors and the ground, substantially as described. Y i.

in a Wireless receivingl station, including a ineens for reducingthe disturbing effects oil static electricity, an antenna, a reeeiving circuit, and means for detectin electro-magnetic Waves 1n combination Wit I two separate concentric sets of conductors, said concentric sets of conductors bein moved from said antenne. and substantially surrounding the's'arue, andmeaus for iinpressing and maintaining charges of electricity of opposite sign respectively upon said concentric sets of conductors. Y

5. ln e Wireless receiving station,v an. antenne and a receiving circuit with means for detecting electro-magnetic Waves in combination with two seperate concentric setsof conductors, said concentric' sets of conductors substantially surrounding said antenna, the distance betwecmsaid concentric sets of conductors being lessi, than the distance between said concentricitsets o ccnductors and said antenne, and ineens for' pressing charges of opposite sign respecltively on said concentric sets of conductors.

6. 'lu a Wireless receiving sta-tion, including a means for reducing,- the disturbing ofy facts oi static electricity, an antenna, o 'receiving circuit and means for detecting electro-magnetic Waves in .combination with two separate sets of concentric conductors, said concentric sets of conductors substantially surrounding said antenna, one of said sets of concentric conductors being connected j through o source of positive electricityto the ground, the other set of concentric con'- ductors being connected through a source of negitive electricity to the ground., substantially es described.

In testimony whereof we beve hereunto set our hands in the presence of two 'subscribing Witnesses.
